What does an art gallery do for an artist? People buy art for a number of reasons, and art galleries are judicious about who a work of art sells to and how that can elevate an artist’s profile. This short film explains how the tricky business of buying and dealing artwork has evolved over time and changed with technology. It’s the second in a series of short films from Artsy and UBS, titled "The Art Market (in Four Parts)," that aims to make sense of the unregulated art world—you can watch the first one, on art auctions, here. The films were directed by Oscar Boyson, and can be seen on Artsy as well as on UBS's online art portal.
